Chemical Structure
Description
The molecular framework of (S)-Rabeprazole Sodium Salt (C18H20N3O3SNa) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
(S)-Rabeprazole Sodium Salt (CAS 171440-19-0), molecular formula C18H20N3O3SNa and molecular weight 381.43 g/mol, is a CATO reference standard with documented purity and traceability.
